Abstract (en)
A method of preventing interference of signals transmitted from electronic input devices to a computer host. An identification is generated for each individual electronic device. A receiving unit is connected to the computer host. The identification frequencies are pre-stored in the receiving unit. The receiving unit performs scanning of signals transmitted from the electronic devices with a scanning cycle. The receiving unit switches between a plurality of detection sequences within each scanning cycle. When signals are transmitted from the electronic devices, the receiving unit receives the signals within the detection sequences corresponding to the electronic devices that transmitting the signals. The identification frequencies carried by the signals are compared to the pre-stored identification frequencies to ensure the signals being received at respective frequency channels. The input data carried by the signals can thus be received and transmitted the input data to the computer host without being interfered. In one embodiment, each of the identification frequencies is modulated with a product identification code, a sub-identification code and the input data
